We look at the division of 200591 by 15 
We want to figure out the number of times 200591 can be divided by 15.

Step 1:
15 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 15

Moving on to step 2:
20 divided by 15 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 15 from 20, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 15

Advancing to step 3:
50 divided by 15 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 45 away from 50, we end up with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 15

On to step 4:
15 goes into 55 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
If we take 45 away from 55, we end up with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 15

Advancing to step 5:
15 goes into 109 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 1337.0
Subtracting 105 from 109 leaves us with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 15

Moving on to step 6:
15 can be fit into 41 2 times, resulting in a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 13372.0
If we subtract 30 from 41, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
When dividing 110 by 15, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 13372.7
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
50 divided by 15 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 13372.73
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 13372.733
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 13372.733 with a remaining 0.0005.
